To ali whom t may concern.'

Beit known ,that I, WILLIAM `STUBBLE- FIELD, a ctizenof :the UnitedStates, and a resident "of `the 4city of St. Louis and State of Missouri, have .-inventedcertain new and useful "Improvements in Step -Molds, .of which the lfollowing is `a specification.

This invention relates to step molds, and has for its-primary ,object to provide `an improved construction, combina-tion and arrangement .of 4parts ina device of .this Acharacter wherein-57 it can be Vmade adjustable angularly in length, .breadth andpitch.

Y A further vobject is to provide certain adjustable Vportions yof improved construction which, when assembled,.constitute an im proved knockdown j. construction for .concrete `steps of .various `sizes and'iorms.

Y More specically, my invention ycontemplates the provision .ci adjustable Sectional side boards, ,riser panels, .tie rods for said side boards and panels, .and improved Vadjustable lsupports"for said side boards. A

Qtherand Afurther objects will appear in the speciiication .and be specifically pointed out inthe appended claims, .reference being had to .the `accompanying .drawings exemplifying `the invention, `and in which,

Referring `more ,particularly -to .the drawings, and first .of -all to the .embodiment shown 4in Figs. 1 .to l2, inclusive: `My invention contemplates a pair of side boards constructed in :sections 1, ,each of .said sections being providedfwth a .top flange A2, a

bottom flange 3, and a lug 4. at.each.end, said them to rest .solidly ,againstthe horizontal Y and vertical surfaces Whilesupporting-the A side .boards at ,any desired angle. In order to provide improved adjustable .means for tying Ythe segments 7 -to the sections 1, l preferably .employ a tie rod (see Fig. 10)

consisting of sections .9., each of said seci tions being provided at one .end .with a threaded socket 10, and Aat .its other fend `with a .threaded stud 1,1. Projecting from the outer face of each section 1, is a fbear.-

ing lug 12 .through which `the tie nod .extends, said bearing being provided .with a set screw 13 for rigidly `clamping lsaid tie rod therein. The loivermost .section of ,the sideboard tie rod :is pivotal-ly .mounted on `the stud 14 lcarried -by the segment i7, and is Aip-rovided `With a pocket l5 for .the receptionfof thesetting-,stake 1,6. fllhemppermost section .of :said tie =rod ;is pivotallt7 mounted onthe stud 17, andis @provided .vv-ith a pocket lS .or a. setting starke 19. With 'the Lconstruction rthus fardescribed, rtheupitch, ofthe steps :to .be formed can `Joe ,predetenmined .at

arranged for by Aembodvirlg more `vor .less .of .the sections l. Qbv-iouslgyizsaid sections l.l

can be ,madeof any desired -:vv-idth. ,Inpr- .derto 4provide suitable means fior mounting .aa plurality of facing fboards ,for .forming .the

.risers of .the steps, l preterably `.empist" a number of gage brackets of the vformshown best in Fig. 7. Each .of said brackets comprises a vertically disposed portion 2O which is hollowed interiorly to provide a socket 21 for receiving'the ends of said riser forming facing boards. Each' bracket -is moreover provided with a clamping arm 22` which depends on the outer face of the side.

apertures 25a formed in the vertical portion 20 of the gage bracket next below (see Fig. 2'). By meansof this arrangement bolts 26 ca nbe passed through the registering apen tures25' and'25 to secure said brackets in positions, adapting them to hold the riser panels or facing boards in positions for molding steps of any desired tread and rise.v

As shown in Fig. 3, each riser panell may be constructed in any desired number of sections 27 releasably joined at their abutting ends 28, sectional tie rods 29 being preferably provided for holding them against relative displacement. For this purpose, each of the sections 27 is provided with a socket 30 for therod 29. Referring now to Figs.

Tand 8, each end section 27 of the riser panel is preferably provided with notches 31 'which engage a lip or fiange 32, thus serving vto maintainthe panel in position. A convenient form for the panel sections is 'the channel shown on the drawings, the notches 31 being out in the flanges 32.

Referring now to the embodimentshown in Figs. 13 to 18, inclusive, should it be desired to construct an improved knock-down form for concrete rsteps to be used between parallel walls 33, or the like, my invention contemplates a plurality of spaced leftliand brackets 34,V and right-hand brackets 35,;'each of said brackets being provided with angular uprights 36, in one flange of which is formed a slot v37 for the reception of a clamping screw 38 which may be re leasablyvsecured by a thumb nut 39- to hold a-riserpanel40. The lower ange of the panel'4`0 is adapted to rest in the stirrup 41 Y projecting rearwardly from the upright 36.

The horizontalarm of each bracket is pro- 'vided with4V apertures 42 which are adapted tobebrought'into register with corresponding yapertures 43 formed in one of the flanges jlofthe upright 36 to adapt the brackets to be secured' together in a manner similar to that'em'ploved in the other embodiment. In

this embodiment, the riser panels 40 abut directly against vthe .walls;33. The riser panels' when mounted in their respective *brackets 34 are held at their proper height anddistance apart byapair of tie rods 45 opposite sidesr of vwhich project studs `47V which are adapted, respectively, to be passed Y through the apertures 42and 43 formed in the adjacent brackets. Thumb nuts 48 provide a handy means for detachably butrig-Y idly connecting the several parts together.

` The elevated ends ofthe rods 45 are held in their elevated positions in anysuitable manner (not shown). V l

In the operation of theembodiment shown in Figs. 1 to 12, when-a side board has been constructed the desired lengthY by mounting a series of sections 1 together on itheir respective tie rods 9, thev flat edge8 of the upper segment 7 is placed against thewall of the building `for which the steps are to be constructed. Then, when the side board has been ladjusted to the desired angle, the locking bolt 51, carried by thegarcuate flange 6 of the lowermost section 1V of theside board (said locking 4'bolt being slidablyjmounted in the circumferential slot 59 of the peripheral flange 49 of the bottom segmentr7),'is locked, thus holding the-side board ati the desired angle. The stakes 16 and 19 are then placed in their respective pockets'15 Vand 18 and driven into the ground, as vshown in Figs. 1,14 and 6. Ast-hess side boards are used in pairs, the other sideboard is assem-V bled and alined similarly *to the one just mentioned. After these side boards have Y' been set up, gage brackets (as shown more clearly in Fig. These brackets are, made right and leftV`= hand, and the vertical portion 20 and clamp-r ing portion 22 thereof are4 adapted Yto straddle theside boards, as shown in Figs.

7) are mounted thereon.

1, 2, 3, 9 and 11. VEach bracket is clamped V to the side board by the clamping screws 23 carried by the clamping portion`22. In-

mounting these brackets, the horizontal arm 24,'which projects from the vertical portion f 20,7is engaged against the outside of the vertical portion 2O ofthe next adj acentbracket. The' elected aperture25 of saidfarm 24 is broughtinto 'register with theelected aperture 25a of the vertical portion20.'v VThen a bolt 26 is passed through the lregistering apertures and locked.l After'these lbrackets have been secured to theside boards,l each end of the riser panels, whichare composed of a number of sections 27 securedztogether, 4

is engaged in the socket 2,1`of each vertical portion 2O of each bracket. It, ofcourse, Vis understood that each bracket on one Vof the side boards is in alinement on the otherside board. r' p s.; Y Y

The forms having'becn adjustedto'the desired position in the mannerindicated in the foregoing description, a foundation 5,2 rof cinders orv othersuitable vmateriahis filled 'in underneath', the forms Vand extended up between the side boards of the mold. `This foundation having been roughly completed on an incline, as shown, the self-hardening material can be introduced successively through the open horizontal panels into the form shown in Fig. 2, the tread surfaces of the steps being finished oli" as the steps are built. When this process is completed, a Hight of steps 53 Will have been formed. Obviously, by means of this apparatus these steps can be made of any desired pitch, rise and tread.
